Claims13
A forced-convection heat exchanger for a rotary electrical machine, comprising one or more tubing elements that are arranged between the conductors of the stator windings of said rotary electrical machine, so as to be in contact with the outer surface of said conductors, a cooling fluid flowing into said cooling elements.
A forced-convection heat exchanger for a rotary electrical machine, according to one or more of the previous claims, characterized by the fact that said one or more tubing elements are operatively connected to pumping means which are suitable to ensure forced convection of said cooling fluid.
A forced-convection heat exchanger for a rotary electrical machine, according to one or more of the preceding claims, characterized in that said tubing elements are made of metallic material.
A forced-convection heat exchanger for a rotary electrical machine, according to one or more of the claims from 1 to 10, characterized in that said tubing elements are made of electrically non-conducting material.
A rotary electrical machine characterized by the fact of comprising a forced-convention heat exchanger according to one or more of the previous claims.
